Case Studies


Silicon bronze alloy

In his search for a suitable material for making mirror frames and tables, blacksmith Oliver Dakers relied on the support of Columbia Metals. He required a material that could be both hot and cold forged and was pointed in the direction of Coldur-A®, a trademark alloy of Columbia Metals.

“The technical help provided by Columbia’s team of specialists enabled me to ensure I could forge and form Coldur-A® silicon bronze into complex shapes and textures,” explains Oliver Dakers. “This was required by the design of the mirror frames, tables and other items I was making. Columbia Metals helped me understand the chemical composition of the alloy so that I could then patinate the finished product in a variety of ways.”

Oliver has used Coldur-A® in sheet and plate form to create bespoke and creative metalwork of the highest standard. “Since this work I have also used Coldur-A® to forge door knockers, handles and jewellery,” he says. “I am still finding more elaborate uses for this highly versatile non-ferrous metal alloy.”
